CARE OF YOUR TELESCOPE

Your telescope should be kept away from dust and moisture. If the lenses get dirty, blow any dust particles off before cleaning. Clean the lenses with a moistened lens tissue. Always store your telescope in the box when not in use.

HELPFUL HINTS FOR SETTING UP YOUR TELESCOPE

1. Unpack the tripod from the box.
2. Stand the tripod up vertically and spread the tripod legs fully apart. Then drag out the extension of the tripod legs to the desired height (at equal lengths) and tighten the locking lever in each leg to maintain it in position.
3. Loosen the knob bolt (9) and the Altitude adjustment handle (10) of the tripod.
   
4. Put the telescope on the tripod by sliding the base of the telescope to the corresponding bracket (14) on the tripod head (as shown).
5. Secure the telescope by tightening the Telescope knob bolt (9) and the Altitude adjustment handle (10).
6. The relatively high magnifying power of the telescope results in a limited field of view. Therefore, finding a particular star or planet desired to observe could be a little hard.
7. Look through the two viewfinders (12) to aid in correctly aiming your telescope. Locating a celestial body via the main telescope becomes less difficult.

OBSERVING ASTRONOMICAL OBJECTS THROUGH YOUR TELESCOPE

1. Glance through the main telescope's eyepiece (6) for your object. (Note: You may have to alter the angle of the telescope slightly.) The object will most likely seem to be blurry at this stage, but that is normal. You are just trying to get the object in the viewing field of your telescope lens. Once you have accomplished this task, fasten the Altitude adjustment handle (10) to keep the accuracy of your telescope steady.
2. Now adjust the focusing tube (5) by turning the focusing knob (8) slowly back and forth until the blurred object becomes sharp.
3. If you are going to be looking through the telescope for a short period of time, you can insert the eyepiece (6) directly into the focusing tube (5). To be more comfortable when using your telescope for longer periods of time, place the diagonal mirror (7) into the focusing tube (5) and the eyepiece (6) into the diagonal mirror.

PUTTING IN THE BARLOW LENS

1. Remove the diagonal mirror (7) and insert the Barlow Lens (15) into the Focusing Tube.
2. Now the Eyepiece can then be inserted into the Barlow Lens. If needed, the diagonal Mirror should be installed between the Barlow Lens and the Eyepiece.

HOW MUCH POWER: CHOOSING THE EYE LENS

Power refers to the ability of a telescope to enlarge an image, or, in effect, bring it closer to the viewer. Amount of magnifying power is signified by a number followed by an X (read "power"). So if you view an object at 20X, you are seeing it as if you are 20 times closer to that object.
Power is calculated by dividing the focal length of your telescope's objective lens (probably indicated on the focus tube) by the focal length of the eye lens you select. The focal length of the eye lens is usually indicated on the eyepiece itself.

The longer the focal length of the eyepiece, the less the magnifying power of the telescope; the shorter the focal length, the greater the power. So when you select an eye lens to insert into the diagonal prism, you're really choosing what magnifying power you wish to use for observation.

Using the smartphone adaptor

1. Loosen the screw at the back of the adaptor and put the smartphone on it with face up.
2. Adjust the position of the horizontal arm to fit the width of the smartphone and tighten the screw just enough to keep the phone in position.
   
3. Align the centre of the adaptor hole of the swing arm to the smartphone camera. Tighten the screw so that the smartphone is securely held in place.
   
4. Loosen the small screw at the top. Attach the adaptor-smartphone assembly to the telescope eyepiece as shown. The adaptor should be fully inserted into the eyepiece for best results. Tighten the small screw
   
5. With the camera app opened, re-adjust the smartphone camera position by slightly loosening the main adaptor screw if necessary. The image circle should be at the centre of the screen. Adjust the focus knob until the image is clear.
